I have just used the steve ward indexer module to engrave a new dial for my lathe. I wanted 100 divs which would be 3.6 deg or 3 deg 48 mins. With the indexer you can either set divs or degrees and it is so simle. I think mine worked out about £80 complete.I bought the module and keyboard from steve. got the case from rapid electronics and the stepper module from ebay. I fitted it all in the case and made my own overlay. I also stuck a 40mm fan inside as well as the heatsinks get a little warm. Power supply came from an old laptop charger.
I have some pics if you are interested.
